I VVALILNUZL,1532130.;IEIIIEIIEtCIiN6: MACHINE A pplication filed September 2e,'-1929. Serial no. 395,325.

I My inlvntiiion relates to Piercing machines and an object of the same is to, provide a,

continuously operated mechanism wherein nuts or other objects will be singly delivered to a reciprocable piercing element. Y

A further object of theinvention is to provide a machine of this character embody-v ing a reciprocatory. piercing element and a rotatable feeding device which is rotated step by step to singly bring the nuts or other ob-- jects into the path of the reciprocating piercing element.

The invention also contemplates a machine of this character whereby large quantities of nuts or other objects will be expeditiously pierced preparatory to placing the same in a preservative.

l/Vith the preceding and other objects and advantages in mlnd, the invention consists in the novel combination of elements, constructions and arrangements of parts and operations 'to be hereinafter more fully described, claimed and illustrated in the acwherein: Figure 1 is a side elevation of the machine; Fig. 2 is a rear elevation of the same; Fig.3 is a perspective of the hopper embodied in the invention; Fig. 4 is a fragmentary vertical section taken on line 4 4 of Fig. 1; Fig. 5 is an enlarged detail view having parts broken away;

Fig. 6 is a top plan view of the machine; Fig. 7 is a fragmentary sectional view of 7 parts of the machine; and

' Fig.8 is a transverse section taken on sub stantially theline 8'-8,of Fig. 6.

Referring to the invention i detail a base 5 is provided from which pairs of vertical posts or uprights 6 arise. v

A horizontal table or shelf 7 is mounted on the upper ends of the legs '6 and as disclosed in Fig. 6 is provided witha central opening or cut out portion 8. Arising from the base and extendingthrough the central opening at the rear end thereof is a pair of parallel standards 9. Secured to the outer face of each of the-standards 9 isa tubular guide 10 in each of which a plunger 11 is mounted for reciprocatory. movement in a or other object into tines .15 a revoluble circular carrier 31 is vertical direction; An angle plate 12.,isat

tachedto thelowe'r end of each of the plung ers and cast therewith is a horizontallyfeX tendingplate l3. Depending from eac'hofthe plates 13 is a row of longitudinallyalined tines orpiercing elements 14 adapted to pass through perforated clearing plates 15 mounted below the plungers 11', the clearing plates having right angular attaching. flanges 16'v a which are secured to the standards as at 17. A- wear plate 18 is attached to each'of the standardsv belo-wthe guides 10 to prevent arecrank arms 20 withwhich pitmanrods 21 are connected. The ,pitman rods-21 extend parallel to the, standards 9. and are pivot-ally connected with the upper ends of the mun ers as at 22.

A main power shaft 23 supported the standards 9flbelow thetable androtatable therewith isa pulley 24 provided with .a

Wear incidentto the movement ofthe plungsprocket wheel 25 at one end. A sprocket chain 26'passes around this sprocket wheel andextends upwardlybetween the standards, and is tra-ined about a larger sprocket wheel 27 fixed to the shaft 19. I

; Power is supplied to the power shaft T23 'fromamotor 28 mounted on the basel5. 1A

drive beltf29 passes around the pulley 24 and a-fsmaller p ulley 30.fiXed to the motor: shaft;

' For the purpose of singly delivering a nut. the path of each set of mounted upon the. table 7adjacent each of the clearing plates 15." As disclosed particularly in Fig, 6 each carrier isformed'with a plurality. of radially disposedpo'ck ets or recesses 32 in the periphery, which areof such size as to receive a nut or other spherical ob-- ject. Blocks 81a are secured to the table to oneside of each of thecarriers and are pro- .vided with semi-circular inner faces'32aembracing the carriers; "For each carrier 31"a drive shaft33is provided: Thedfive shafts loo i extend vertically throughthe-table and are gages the ratchet wheel.

fixed to the carriers. A bevelled gear 34 is fixed to the lower end of each of the shafts 33 and is engaged by bevelled gears 35 fixed to shafts 36, the latter being 'journalled in the standards 9.

In order to rotate the carriers step by step to successively bring the pockets 32 in vertical alinement with the tines 14 a ratchet wheel 37 is fixed to the inner end of each of the shafts 36. An arm 38 is pivotally mounted on the inner end of each of these shafts 36 and carries a spring pressed pawl 39 which en- F or each of the arms 38 a vertically extending actuating rod 40 is provided and has its lower end pivoted to the outer end of one of the arms 38 and its upper end pivotally connected with a lever 41, the levers 41 being pivotally supported from angularly extending arms 42 fixed to the upper ends of the standards 9. Botatable with the shaft 19 in vertical alignment with the levers 41 are arms 42 carrying rollers 43' at their outer ends which are adapted to engage the levers 41 to lift the same. It will be observed that upon each revolution of the arms 42 the levers 41 will be lifted and in turn raise the arms 48 to engage the pawls 39 with their respective ratchet wheels and rotate the same a predetermined distance. In turn the carriers 31 are rotated through the instrumentality'of the shafts 33 to cause their pockets to successively register with the tines 14.

In order to normally hold the carriers stationary a spring pressed plunger 45 is mounted in a casing 46 at one side of each carrier. A disk 47 is secured to the under face of each carrier and is provided with notches 48 which register with pockets 32. A series of notches 49 is provided in each disk and are adapted to successively engage one of the plungers 45.

The nuts or other objects are fed to the carriers from a rectangular tray or hopper 50 Which extends entirely across the rear end of the table 7. The hopper is provided with an inverted V-shape'cl bottom 51 which is inclined toward the front wall of the hopper to cause the objects to feed through outletopenings 52 and roll onto the plate 7. The rear and side walls of the hopper overlap the rear and side edges of the table to retain the hopper thereon. In the operation of the invention the nuts or other objects rolling on to the table 7 are individually received in the pockets of the rotating carriers. In this connection it is pointedout that the pockets and outlet openings 52 are so positioned relative to each other that each nut rolling from the hopper is confined in one of the pockets. Continued rotation of the carriers successively brings the nuts below the reciprocating plungers. At this time the V descending plunger causes the tines to penetrate the nuts. As the carriers rotate the pierced nuts are discharged through openings 53 providedin the table at points diametrically opposite the tines 14. In actual practice suitable receptacles will be positioned below the openings 53 to receive the pierced nuts falling therethrough.

I claim:

In combination a base, a reciprocatory piercing element mounted above the same, a

perforated clearing plate supported below the piercing element, a shaft supported above the piercing element and having operative connection therewith, a carrier supported below the clearing plate, a shaft operatively connected with the, carrier, a pawl and ratchet CHARLES. W. EDWARDS.
